If we use Qt5 5.13.0 to compile this program, QObject::trUtf8 is deprecated. And in the file "Modules/AppUtil/src/QmitkSafeNotify.h", it has the uses of app->trUtf8 with only ASCII character inside it. So I want you to change these lines
(Line 53, 54)
```
msgBox.addButton(app->trUtf8("Exit immediately"), QMessageBox::YesRole);
msgBox.addButton(app->trUtf8("Ignore"), QMessageBox::NoRole);
```
into
```
msgBox.addButton("Exit immediately", QMessageBox::YesRole);
msgBox.addButton("Ignore", QMessageBox::NoRole);
```
